Two ways to work together: by the day, or on results.

FinOps and cloud architecture, with cost treated as a design constraint. Join forces by the day, or let me cut your bill and pay me only on what goes down. And training for your team.

01 · Régie

On your team, by the day.

FinOps or cloud architecture: the same availability and the same daily rate for both.

FinOps engineer

Your cloud bill, worked on from inside the team.

  • Audits of the bill, with the savings priced item by item
  • The changes your team approves, applied with your engineers
  • Cost priced at the design stage, before it is built

Pick it when you want the work done inside the team, on the priorities you set, rather than a fee on the savings.

Cloud architect

Architecture, with cost as a design constraint.

  • Multi-cloud and disaster recovery designs on AWS, Azure and Google Cloud
  • Migrations and performance work, with the legacy system as the test reference
  • Infrastructure as code and security: Terraform, policy as code, identity

Pick it when you have a platform to design, migrate or speed up, and every option should come with its monthly cost.

Teach your team to cut its cloud costs.

Three formats, from a half-day session to a two-day bootcamp. Delivered in English or French.

Half a day

Awareness session

€1,500 for up to 15 people

Everyone shares one vocabulary: how the bill is built, where cloud spend usually hides, and which levers exist.

One day

Hands-on workshop

€3,500 for up to 10 people, preparation included

The team reads its own bills and leaves with a prioritized list of savings it can act on.

Two days

Practitioner bootcamp

€7,000 for up to 8 people, preparation included

Practitioners can run the cost practice: analysis, commitments, allocation and unit economics, with cost in every design review.

Prices excl. VAT, per group. €150 per extra participant. Travel outside Paris charged at cost.
